Plastic shrinkage cracks are relatively short cracks that can occur prior to finishing. Specifically, if the panel is exposed to wind, high temperatures, or low humidity.Heaving cracks in concrete refer to cracks that result from the upward movement or displacement of concrete, leading to a visible separation or opening. These cracks typically form when there is a significant increase in volume within the concrete mass, exerting pressure and causing it to heave or rise.

The crack information can be used to decide the appropriate rehabilitation method to fix the cracked structures and prevent any catastrophic failure. In practice, cracks on concrete surfaces are traced manually for diagnosis. On the other hand, automatic crack detection is highly desirable for efficient and objective crack assessment.
